“…Of these, it was possible to identify 31 larvae and 27 nymphs of Amblyomma longirostre (Koch, 1844), 17 nymphs of A. nodosum (Neumann, 1899), one A. cajennense (Fabricius, 1787) larva, and one male Rhipicephalus sanguineus (Latreille, 1806) ( Table 1). This R. sanguineus specimen was previously reported elsewhere (SZABÓ et al, 2008). All other ticks were identified as Amblyomma sp.…”

“…This is a relevant finding since A. cajennense is a major known vector of Rocky Mountain spotted fever agent, Rickettsia rickettsii (LABRUNA, 2009), in Brazil and is the host-seeking tick significantly captured in the cerrado biome (SZABÓ et al, 2007;VERONEZ et al, 2010). At the same time the finding of an adult R. sanguineus, a dog tick, on C. flaveola was unexpected, probably accidental, but it warrants future awareness (SZABÓ et al, 2008) as this species is of paramount importance due to its ability to transmit major pathogenic agents, such Ehrliquia canis, to its hosts (MACHADO, 2004).…”

This is a report of ticks species, parasite prevalence and infestation intensity of birds in a forest fragment (18° 56' 57" S and 48° 12' 14" W) within the Brazilian cerrado (savanna), in the municipality of Uberlândia, State of Minas Gerais, Brazil. A total of 162 birds from 26 species were captured. One adult tick, 296 larvae and 67 nymphs were found on passerine birds. Of these, it was identified 31 larvae and 27 nymphs of Amblyomma longirostre, 17 nymphs of A. nodosum, one A. cajennense larvae and one male of Rhipicephalus sanguineus. All other ticks were identified as Amblyomma sp. larvae (n = 264) or nymphs (n = 26). Overall tick infestation intensity and prevalence were 4.32 ticks/infested bird and 52%, respectively. Sampling of host-seeking ticks on the ground within the forest during a two-year period showed only five Amblyomma sp. nymphs and one adult male of A. nodosum whereas a search for ticks on domestic animals (cattle, horses and dogs) found Rhipicephalus (Boophilus) microplus ticks. Although identification was possible in only 27% of bird ticks there seemed to be no correlation between environmental and domestic animal and bird infestation. It can be assumed that bird infestation may occur above the ground or at specific sites not sampled.Keywords: Bird, tick, Ixodidae, Brazilian savanna. ResumoNeste trabalho, são apresentadas as espécies de carrapatos em aves silvestres, sua prevalência e a intensidade de infestação em um fragmento florestal (18° 56' 57" S e 48° 12' 14" W) do Cerrado, no município de Uberlândia, Estado de Minas Gerais. Foram capturadas 162 aves de 26 espécies, mas apenas as aves Passeriformes estavam infestadas. Nestas, foram encontrados um carrapato adulto, 67 ninfas e 296 larvas. Dentre os carrapatos foi possível a identificação de 31 larvas e 27 ninfas de Amblyomma longirostre, 17 ninfas de A. nodosum, uma larva de A. cajennense e um Rhipicephalus sanguineus macho. Todos os outros carrapatos foram classificados como larvas (n = 264) ou ninfas (n = 26) de Amblyomma sp. A intensidade de infestação e a prevalência de carrapatos foram de 4,32 carrapatos/ave infestada e 52%, respectivamente. Na pesquisa de carrapatos em vida livre sobre a vegetação do fragmento florestal, foram capturados apenas cinco ninfas de Amblyomma sp. e um macho adulto de A. nodosum, por um período de dois anos. Carrapatos da espécie Rhipicephalus (Boophilus) microplus foram encontrados parasitando bovinos, cavalos e cães domésticos da região. Mesmo considerando a identificação de apenas 27% dos carrapatos das aves, parece não haver correlação entre infestação ambiental, nos animais domésticos, com a infestação das aves. Pode-se supor que a infestação das aves ocorra acima do solo ou em locais específicos não pesquisados neste trabalho.Palavras-chave: Ave, carrapato, Ixodidae, cerrado.

“…At the same time it has been described previously from dogs only once in Brazil (SABATINI et al, 2010). Birds may actually deliver ticks the other way round, picking them up in rural/urban areas (SZABÓ et al, 2008). This linking ability of birds is possibly encouraged by human activities such as, in the case reported here, the owner's bird feeding habit, which is very common human behavior.…”

Amblyomma nodosum (Acari: Ixodidae) parasitizing a domestic dog in Colatina, Espírito Santo, Brazil

On 27 Jan 2011 an adult Amblyomma nodosum tick was found attached to a domestic dog from the municipality of Colatina, state of Espírito Santo, Brazil. This is the first report of this tick species in this state and the second time it has been reported parasitizing a domestic dog in the country. For the time being, this finding should be regarded as incidental. However, more in-depth research into the hosts and ecology of A. nodosum is needed, since it has been associated to infectious agents that are potentially pathogenic for humans.

“…Despite such avian diversity, only 3 tick species are known in Brazil to use birds as primary hosts for all parasitic stages: Argas miniatus Koch, 1844, a parasite of domestic fowl, and Ixodes auritulus Neumann, 1904 and Ixodes paranaensis BarrosBattesti, Arzua, Pichorim & Keirans, 2003, parasites of wild birds (Arzua et al 1994, Arzua & Barros-Battesti 1999, Dantas-Torres et al 2009). Curiously, accidental infestations by Rhipicephalus sanguineus (Latreille, 1806) have been reported on native and nonnative birds in Brazil (Diogo et al 2003, Szabó et al 2008. For the most part, however, studies have reported the occurrence of immature stages (larvae and nymphs) of Amblyomma spp.…”

The Amazon biome harbors the richest avifauna in the world. However, in the Brazilian Amazon only a single previous study has systematically evaluated wild birds for ticks. During 2012, wild birds were captured in two areas of the Brazilian Amazon forest, one located in the State of Amazonas, and another in the State of Pará. Overall, 581 wild birds representing 118 species were captured, but only 18 individuals (3.1% prevalence) were infested by ticks, comprising immature stages of Amblyomma calcaratum Neumann, 1899, Amblyomma geayi Neumann, 1899, Amblyomma humerale Koch, 1844, and Amblyomma longirostre (Koch, 1844). The only previous study of birds in the Brazilian Amazon reported 40.2% tick prevalence. Such contrasting prevalence values may stem from seasonal differences or differences in forest disturbance at the two sites.
